well, start by not making random pixels and dithers. as for a good way to get the texture to be credible, look on any of the examples on the site. there might be two or three games that feature stone statues with textures(metal slug for example) that might give you an idea.

also, before someone points at the outline, i'd like to hear your own explanation as to why you think it looks right.
